Air purifiers, also known as "air purifiers", air fresheners, and purifiers, refer to products that can adsorb, decompose, or transform various air pollutants (generally including decoration pollutants such as PM2.5, dust, pollen, odors, formaldehyde, bacteria, allergens, etc.), effectively improving air cleanliness. They are mainly divided into household, commercial, industrial, and building products. There are various technologies and media in air purifiers that enable them to provide users with clean and safe air. Commonly used air purification technologies include adsorption technology, negative (positive) ion technology, catalysis technology, photocatalyst technology, superstructure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc; The material technology mainly includes photocatalysts, activated carbon, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. The existing air purifiers are mostly composite types, which adopt multiple purification technologies and material media simultaneously
